The 190 deg F. thermostat will give you an idle temperature in that area of 190 - 195 Deg as will be read from a scan tool. Your temperature gauge on the truck however should read at 210 for normal .... slightly higher when going up long hills under load. The Gauge has will read lower at normal operating temps if your thermostat is in the stuck open position and the thermostat must be replaced as these trucks do not get good mileage unless they are at 190 deg. For Canadians It should be at 100 deg C. Again I must say that all the gauges are controlled by the PCM and display the reading as dictated by the PCM. The PCM gives them incremental information based on complex algorythms developed at GM that give you BASIC information and is not degree accurate. The closest gauge is your Speedometer ....as you know that that would have a negative effecr on your wallet if it was the local Police had you on radar.
